OpenAI announced on Thursday that it now has over 1 million paying users across its ChatGPT business products, including Enterprise, Team, and Edu. The increase from 600,000 users in April highlights CEO Sam Altman’s success in driving enterprise adoption of the AI tool.

Recent reports suggest OpenAI executives are discussing premium subscriptions for upcoming large-language models, such as the reasoning-focused Strawberry and a new flagship model called Orion. Subscription prices could reach as high as $2,000 per month for these advanced AI tools.

ChatGPT Plus currently costs $20 per month, while the free tier continues to be used by hundreds of millions every month. OpenAI is also working on Strawberry to enable its AI models to perform deep research, refining them after their initial training.

The discussion around premium pricing follows news that Apple and Nvidia are in talks to invest in OpenAI, with the AI company expected to be valued at over $100 billion. ChatGPT currently has more than 200 million weekly active users, doubling its user base since last autumn.
